Preheat your oven to 325°F and prepare a baking sheet by lining it with parchment paper.
In a small bowl, melt the butter and allow it to cool slightly.
Combine the 1 cup sourdough discard, 2 tablespoon melted butter, ½ teaspoon sea salt, 2 teaspoon dried herbs, 2 tablespoon nutritional yeast, and mix thoroughly until well incorporated.
Spread the mixture evenly onto the prepared parchment paper — this is a liquidy mixture, so you can use an offset spatula like you're frosting a cake. A quick spray with cooking oil can help prevent sticking, I've found. Sprinkle lightly with flaky sea salt (I use Maldon).
Bake for 10 minutes, then remove from the oven and score the crackers lightly so they're easy to break up when finished. Continue baking for an additional 20 minutes, and begin checking for doneness. The edges will brown first, so it's not uncommon to remove the edge pieces and let the inner ones continue baking for up to 35 minutes total.
Allow the crackers to cool completely before breaking them into squares.
Store in airtight container for a week, but I can guarantee they'll be gone long before then!
